$ ls -d /var/lo*
/var/local  /var/lock  /var/log  /var/lost+found

C-x d / v a r / l o <return> C-x C-r / v a r / l o <return> <return>

Consider the treatment one gets on the first <return> vs. the second
and third.  The former is like tough luck bub, whereas the latter is
VIP helping environment warm & fuzzy.

I believe this all comes back to the fact that there is only a single
`interactive' character code for reading a directory ("D"), and so
there isn't a way to distinguish between an existing directory and a
possibly nonexistent directory (cf. "f" and "F" for files).  Neither
is there a read-directory-name analogue for read-file-name, which
accepts an optional MUSTMATCH argument.
